# Module Cf_journal.T.Priority

    module Priority: Cf_ordered.Total_T

The module used to define the total order of priority levels.

    type t

An abstract type

    val compare : t -> t -> int

`compare a b` compares the total ordering of `a` and `b`, and it returns zero if the two values are of equal total order, a negative integer if `a` follows `b`, and a positive integer if `a` precedes `b` in the total ordering. The `Pervasives.compare` function is a suitable value in modules of this type.
